For me personally, I don't do much file work as I mostly make Culinary knives and file work can harbor food etc, So even thou it looks great I think the purpose of the knife and keeping things sanitary are most important.
I've been into knives since a little boy and recently started making my own (as a hobby). Started with files and recently got my first grinder to learn on (Craftsman 2x42). Still don't have much of a clue, but know a little more than I did when I was 12.
